Apple today released the first developer beta for iOS 13.4.5. Apple last week released iOS 13.4 and iPadOS 13.4 with many new features, the release notes suggest this update is to focus on bug fixes and performance improvements, but there were some small changes cited by many on the internet for example now you can share the music you are listening to on Apple Music to Instagram and Facebook stories.
To check this feature out hit on the share button from the “now playing” page and select Instagram, this will automatically create a story post that will have the album cover, name of the song and a blurred animation in the background, this will be displayed as your story and people who view it can click on the song and can listen to it on their devices.
Along with iOS 13.4.5, Apple has also released iPadOS 13.4.5, macOS 10.15.5 (Catalina) and tvOS 13.4.5. No watchOS though.
